qcacmn: Support for RF path selection

Includes changes:
1. Save frequency values from EXT and EXT2 events to psoc object
- wireless_modes, low/high 2 GHz chan and low/high 5 GHz chan from EXT event
- wireless_modes_ext, similar frequency range fields with _ext from EXT2
event. Frequency range fields with _ext are non-zero when a radio supports
overlapping frequency. Eg.Radio that supports 5 GHz full and 5 GHz high band will
have low/high 5 GHz fields populated with primary band values in EXT event and
low/high 5 GHz fields are populated in EXT2 event with secondary band
values. These values are stored in tgt info for later use.
2. Modify regulatory APIs to get and set the wireless modes in reg
component
3. Retrieve frequency fields from EXT2 event
